Description
Technical field
This utility model relates to software oxygen cabin structure technical field, particularly, relates to a kind of software oxygen cabin of adapted oxygenerator.
Background technology
Software oxygen cabin is a kind of employing air pressurized, breathes air in the cabin, is used to treat, the manned airtight air bag of health care, first aid.It is compared with steel oxygen cabin, has characteristics such as simple to operate, safe in utilization, cheap, easy to carry, is more suitable for being used for family, clinic and field.But better and curative effect are faster hoped to obtain in software oxygen cabin, need the adapted oxygenerator, with the partial pressure of oxygen in the further raising environmental gas., oxygenerator directly is connected with software oxygen cabin, and respiratory resistance is excessive in the time of can causing suction oxygen, even causes pulmonary barotrauma, in addition, owing to breathe with strength, oxygen in the oxygen face mask is bled in the cabin during use, is easy to take place to catch fire in the cabin.
The utility model content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, provide a kind of can with oxygenerator supporting, the safe handling software oxygen cabin.
The technical scheme that realizes above-mentioned purpose is following:
A kind of software oxygen cabin of adapted oxygenerator; Comprise the cabin body; The cabin body is provided with airtight slide fastener, Pressure gauge, ventilation choke valve, charge valve, air bleeding valve, in the body of cabin, is provided with oxygen face mask, oxygen supply pipe and oxygen discharging tube and the cabin bulk phase company of oxygen face mask through having one-way control valve respectively; External electrodynamic pump and the oxygenerator of being provided with in the cabin; Said electrodynamic pump links to each other with charge valve through gas tube, and said oxygenerator links to each other with oxygen face mask through the oxygen supply pipe, on the oxygen supply pipe of said oxygen face mask and oxygen discharging tube, also is respectively arranged with confession, deoxygenation adjusting device; The external oxygen detection device that is used to detect oxygen volume fraction in the body of cabin that also is provided with also is provided with on the gas tube between said electrodynamic pump and the charge valve and fills the ventilation conversion equipment in said cabin.
Further; Oxygen supply adjusting device in said confession, the deoxygenation adjusting device comprises oxygen supply choke valve, the oxygen flow meter that is arranged on the oxygen supply pipe, and the deoxygenation adjusting device in said confession, the deoxygenation adjusting device comprises breathing bag, deoxygenation choke valve, the deoxygenation effusion meter that is arranged on the oxygen discharging tube.
Further, said oxygen detection device comprises sampling tube and is arranged on sampling valve, sampling choke valve, sampling flow meter and the oxygen analyser on the sampling tube that said sampling tube and cabin bulk phase connect.
Further, the said ventilation conversion equipment that fills comprises carbon filter, permutator and the check valve that is arranged on the gas tube, also is provided with the scavenge trunk parallelly connected with gas tube at the upper reaches of permutator, and scavenge trunk is provided with air control shutter and mass air flow sensor.
In this utility model, being provided with of confession, deoxygenation adjusting device can make oxygenerator output pressure, cabin internal pressure, deoxygenation pressure three coupling, the respiratory resistance when reducing suction oxygen.In addition, the oxygen detection device, can the continuous monitoring cabin in the volume fraction of oxygen in the gas; When volume fraction value of being above standard of oxygen in the gas in the cabin; Through regulating the ventilation choke valve and filling the ventilation conversion equipment, make in the cabin that the volume fraction of oxygen is no more than 23% in the gas, the volume fraction that oxygen can not take place is too high and cause the situation of catching fire; The setting of simultaneously, filling the ventilation conversion equipment also can be guaranteed the cleaning of forced air.
Compared with prior art, this utility model has increased confession, deoxygenation adjusting device on basis, software oxygen cabin, the oxygen detection device with fill the ventilation conversion equipment.Thereby, the purpose that has realized in software oxygen cabin, inhaling oxygen rich gas.Patient's respiratory resistance during suction oxygen in the cabin is very little, and the volume fraction and the partial pressure of oxygen that suck oxygen in the gas can be adjusted within the specific limits easily.This utility model is simple in structure, easy to operate, safe, has good practical value.
Through accompanying drawing and embodiment, the technical scheme of this utility model is done further detailed description below.
Description of drawings

As shown in Figure 4; Fill the ventilation conversion equipment and comprise carbon filter 24, permutator 25 and the check valve 26 that is arranged on the gas tube; The upper reaches at permutator 25 also are provided with the scavenge trunk parallelly connected with gas tube, and scavenge trunk is provided with air control shutter 27 and mass air flow sensor 28.
The method for using in the software oxygen cabin of the adapted oxygenerator of this utility model is:
After the people advanced cabin, software oxygen cabin body 1, airtight slide fastener 11 closed.Start electrodynamic pump 8, through 1 pressurization of 10 pairs of cabin bodies of charge valve.Observe Pressure gauge 2, when the cabin press reach setting pressure (for example 30kPa) after, convert the permutator 25 that fills ventilation conversion equipment 9 into ventilation grade by the inflation shelves.Simultaneously, regulate the aperture of the ventilation choke valve 4 on the cabin, the cabin is pressed keep constant.Then, start oxygenerator 7, in (2～5) L/min scope, select required oxygen flow.Personnel put on oxygen face mask 13 in the cabin.Regulate the deoxygenation flow to the 7L/min.During oxygen uptake, only need to keep watch on oxygen detection device 5.When slow ascendant trend being arranged, can increase ventilation volume slightly like the volume fraction of oxygen in the cabin body 1.When treatment arrives setting-up time (for example 60min), take off oxygen face mask 13, close oxygenerator 7, open air bleeding valve 6, the cabin exhaust decompression.When the cabin is decompressed to normal pressure, draw back airtight slide fastener 11, people's deliver from vault.In whole process, can be through personnel's in observation window 3 astrodomes situation.
If will change the patient sucks oxygen in the gas in the cabin volume fraction, can realize through the aperture size of regulating oxygen supply choke valve 15.When oxygen flow changes in (2～5) L/min scope, the volume fraction that sucks oxygen in the gas will change in 40%～90% scope.If oxygen flow is big more, then the volume fraction of patient's oxygen intake in the cabin is high more, and the partial pressure of oxygen that sucks in the gas is also high more.When the cabin was pressed to 20kPa, the partial pressure of oxygen adjustable extent was (48～108) kPa in the suction gas; When the cabin was pressed to 30kPa, the partial pressure of oxygen adjustable extent was (52～117) kPa in the suction gas.
What should explain at last is: the above is merely the preferred embodiment of this utility model; Be not limited to this utility model; Although this utility model has been carried out detailed explanation with reference to previous embodiment; For a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within the spirit and principle of this utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of this utility model.
